Generate correctly formatted random email addresses in bulk, with customizable domains and prefix rules — ideal for testing sign-ups and protecting privacy.
Click generate to create a batch of emails
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
This tool creates a list of email-address-shaped strings for test fixtures, prototypes, and sample data. You set the batch count, local-part length range, character types, and one or more domains. Results can be copied as a list or downloaded as TXT or CSV. The default selected domain is example.com; example.net and example.org are also available as reserved example domains.
An address has a local part before the at sign and a domain after it. The generator chooses a random length in your configured range, builds the local part from enabled lowercase letters, uppercase letters, digits, and optional period, underscore, or hyphen characters, then chooses one selected domain. The first local-part character is a letter. Each row is generated independently, so repeated strings are possible.
Email syntax rules vary by context. RFC 5322 defines a broad message-address format, while delivery systems may apply additional constraints. This generator does not validate a domain's DNS or prove an address can receive mail.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Set a count from the available range control. The maximum displayed depends on the account's batch allowance.
Adjust minimum and maximum length, then enable the character groups needed by your test. If none are selected, generation cannot proceed; the local part starts with a letter.
Keep an example domain for fixtures that should not target a real mail service, or add a domain you control for an isolated internal test. A custom domain is not checked for existence or mail configuration.
Generation refreshes the visible batch. Copy all rows, download a plain TXT list, or download a CSV with row number and address columns.
Use cases
See how the tool fits into real work and everyday tasks.
A QA engineer needs varied local-part lengths to exercise input handling. Generate a small batch with the desired character settings, then use it in a test environment that does not send real mail.
A developer or instructor can copy rows or export CSV/TXT to seed a non-production dataset. Review for duplicates before a test that requires unique keys.
Q&A
Find concise answers to common questions and confusing cases.
No inbox is created. A reserved example domain is for sample use, and a custom domain only changes the text generated; it does not provision mailboxes.
No. The tool generates each row independently and does not deduplicate the batch. Check for repeats or generate another list if uniqueness is required.
No universal guarantee is made. Syntax acceptance varies between validators and services, especially when optional punctuation is enabled. Test with the same validation rules used by your application.
The CSV has a row number and an email column. TXT contains one generated address per line.
Notes
Review scope, result limitations, and important precautions before use.
Use these outputs as sample strings, not as disposable inboxes, delivery targets, or campaign recipient lists. Even when you enter a domain you control, the generator does not create accounts, check DNS, receive messages, or confirm consent. Random generation also does not guarantee uniqueness or compliance with every site's address rules. Review test data before importing it into any system that can send mail.
